The title is misleading. This isn't a cloud app. The current Office 365 Preview is a desktop app with cloud syncing, that requires WIndows 7 or 8. Reference: http://www.microsoft.com/office/preview/en/office-365-enterp...

* No iPad / Android tablet

* No access where you want without a lengthy installation

* No live collaboration.

It's just the same old office with Cloud lip service via a dropbox like service. Not sure why Wired thinks that's 'serious about the cloud'.

MS should just buy Zoho already.

Office 365 runs in a browser. I'm not sure why they're not highlighting that on the page you link, but I assume it's because they're also punting OFfice on Demand (citrix-style streaming)

Yes, but it requires Windows 7 or 8 ,defeating the purpose. Just like the current Office 365.
